Bouncing off the Walls – How Real-Time Radar is Accelerating the Development of Autonomous Vehicles

Bouncing off the Walls – How Real-Time Radar is Accelerating the Development of Autonomous Vehicles
by Jeffrey Decker on 04-01-2021 at 6:00 am

object detection

In the race to get people out of the driver’s seat, the developers of autonomous vehicles (AV) and advanced driving assistance systems (ADAS) have gone off road and into the virtual world.

Using simulation to design, train and validate the brains behind self-driving cars — the neural networks of sensors and systems that perceive… Read More

automotive radar antenna array module

So you’ve decided to buy a new car? First you need to research, compare, and test drive before you finally get to drive that shiny new car home. Engineering teams choosing their preferred electromagnetic analysis tool face similar challenges. Historically, electromagnetic problems and analysis tools were relegated to a few … Read More


Electromagnetic and Circuit RLCK Extraction and Simulation for Advanced Silicon, Interposers and Package Designs

Electromagnetic and Circuit RLCK Extraction and Simulation for Advanced Silicon, Interposers and Package Designs
by Tom Dillinger on 03-16-2021 at 6:00 am

spiral complex

For years, there have been rather distinct domains for the extraction of interconnect models from physical design data.

Chip designers commonly focused on RC parasitics for circuit/path delay calculations and dynamic I*R voltage drop analysis.  The annotation of extracted parasitics to a netlist model required the layout… Read More

RaptorH in Virtuoso

Electromagnetic (EM) simulations have been performed on die metal structures since the 1990s. Originally, the analysis was restricted to a single device (e.g., a spiral inductor). The number of on-die devices simulated simultaneously grew with the increasing capabilities of the computers performing the computations. This… Read More

Webinar: Electrothermal Signoff for 2.5D and 3D IC Systems
by Mike Gianfagna on 02-08-2021 at 6:00 am

Webinar Electrothermal Signoff for 2.5D and 3D IC Systems

The move from single-chip design to system-in-package design has created many challenges. The rise of 2.5D and 3D technology has set the stage for this. Beyond the modeling requirements and the need for ecosystem collaboration to get those models, there is a significant challenge in understanding the data. The only way to truly… Read More

HFSS Performance for “Almost Free”
by Jim DeLap on 12-11-2020 at 10:00 am

HFSS PCB

Everyday, engineers are running simulations to deliver the next generation of products to make our lives better. Everyday, they wait for those simulations to finish, wishing that they could get answers instantaneously. While waiting for those simulations or checking on the status of their runs at night, they might indulge in… Read More


The History and Significance of Power Optimization, According to Jim Hogan

The History and Significance of Power Optimization, According to Jim Hogan
by Mike Gianfagna on 11-13-2020 at 10:00 am

Jim Hogan

Power seems to be on everyone’s mind these days. Hyperscale data centers worry about operating costs unless power is optimized. The AI accelerators in the Edge can’t be effective without optimized power. Advanced 2.5 and 3D packages simply can’t remove the heat unless power is optimized.  And then there’s all those gadgets we … Read More
